Are Turtle boards already available for purchase for interested developers?

J32 would be equivalent to SH4, wouldn't it? If yes, I'm really looking
forward to that. Having new SH4 hardware available for purchase would
help Debian's sh4 port (of which I am the principal maintainer of) and
NetBSD's port for sh3/sh4.

For Debian, I'm currently building most packages for sh4 using qemu-user
which has some bugs meaning that not all packages build fine which other-
wise build fine on real hardware. So, I'm really looking forward for new
sh4-compatible hardware.
